public enum MessageBoxOptions

Member nameDescription

The message box is displayed on the active desktop.


The message box text is right-aligned.


Specifies that the message box text is displayed with right to left reading order.


The message box is displayed on the active desktop.

This enumeration is used by the MessageBox class.

If you do not want to specify this parameter when calling methods on MessageBox, you can pass in 0 instead.

The following code example demonstrates how to display a MessageBox with the options supported by this overload of Show. After verifying that a string variable, ServerName, is empty, the example displays a MessageBox with a question box icon, offering the user the option to cancel the operation. The example uses the RightAlign member of the MessageBoxOptions enumeration to align the text to the right edge of the dialog box. If the Show method's return value evaluates to Yes, the form that displayed the MessageBox is closed.

private void validateUserEntry2()

	// Checks the value of the text.

	if(serverName.Text.Length == 0)

		// Initializes the variables to pass to the MessageBox.Show method.

		string message = "You did not enter a server name. Cancel this operation?";
		string caption = "No Server Name Specified";
		MessageBoxButtons buttons = MessageBoxButtons.YesNo;
		DialogResult result;

		// Displays the MessageBox.

		result = MessageBox.Show(this, message, caption, buttons,
			MessageBoxIcon.Question, MessageBoxDefaultButton.Button1, 

		if(result == DialogResult.Yes)

			// Closes the parent form.
